Macular Degeneration

Concerned About Macular Degeneration? – Here Are 6 Tips to Lower your Risk

What Is Macular Degeneration?

Age-related macular degeneration (AMD) is a deterioration of the macula, the key part of the retina responsible for highly detailed vision and central vision. There are two main types of macular degeneration: dry and wet.

Dry AMD occurs when small deposits in the macula called drusen gradually damage the light-sensitive retinal nerve cells, leading to vision loss.

In wet AMD, fragile new blood vessels grow under the macula. When these blood vessels leak blood or fluid, it damages the macula. Although both types of macular degeneration can result in vision loss, wet AMD is the more serious form of the disease as it results in faster and greater vision loss.

Who Is At High Risk for Macular Degeneration?

  • age 50+
  • a diet high in saturated fat
  • Smoking
  • High blood pressure
  • Obesity
  • Family history of AMD
  • Cardiovascular disease

6 Ways to Reduce Your Risk of Macular Degeneration

The following have been shown to lower the risk of developing AMD:

Stop smoking

If you don’t smoke, don’t start, and if you smoke—quit. Smokers are 4 times more at risk of developing AMD and typically develop the disease around 10 years earlier than non-smokers.

Wear Quality Sunglasses

UV rays from sunlight can put your eyes at risk. So make sure you choose high-quality 100% UVA & UBV filtering sunglasses to block the sun’s harmful UV rays. Consider getting polarized lenses, as they filter out reflected light rays more efficiently. That’s especially important if you spend time on the water, at the beach, in the snow or driving.

Check Your Blood Pressure

High blood pressure not only harms your heart, but restricts oxygenated blood from reaching your eyes. Have your blood pressure checked regularly. If you already have hypertension, consider using an at-home monitor to keep tabs on it.

Eat Healthy and Consider Supplements

Cut out saturated fat, which can raise your blood pressure. Eat fewer animal fats and replace butter with olive oil. Look for plant-based, high-protein alternatives to meat, and eat oily fish like sardines, mackerel and salmon.

Dark, leafy greens are terrific for your eyes. Kale and other greens are full of lutein and zeaxanthin, antioxidants that promote eye health. If you have dry AMD, ask your optometrist about antioxidant supplements that can slow AMD’s progression.

Know Your Family History

Up to 70% of AMD cases have a genetic component. People with a parent or sibling with AMD have a greater risk of developing this serious sight-threatening eye disease. If you have a family history of this disease, get your eyes frequent eye tested for AMD.

Get Your Eyes Checked Regularly

Everyone should have regular comprehensive eye exams, especially if you’re over 50, have a family history of AMD, hypertension or other risk factors.

An eye exam that screens for AMD typically includes:

  • Visual Acuity – tests your ability to read and see an eye chart from various distances
  • Pupil Dilation – the optometrist applies eye drops to dilate the pupil so they can examine the inside of your eyes
  • Digital Retina Image and/or OCT – full color 3D imaging of the macula to detect leakage from the vessels and measure retinal thickness. This can help the eye doctor diagnose wet AMD, even in the early phases.
  • Amsler Grid – The optometrist asks the patient how straight lines on a checkerboard grid appear. The answer “wavy” or “missing” could indicate the presence dry or wet AMD.

Your vision is your gateway to the world. Good vision lets you live an active and independent life, even in your advanced years. Regardless of your age, get your eyes checked regularly, and all the more frequently if you have a family history of AMD or other risk factors.

FAQ

What percentage of the population has macular degeneration?

An estimated 8.7% of the global population has macular degeneration. This number is expected to increase from the current 196 million people affected to 288 million by 2040.

Do injections work for wet macular degeneration?

When AMD has progressed to the “wet” phase, anti-VEGF injections can preserve remaining vision by reducing fluid leakage and bleeding from the macular blood vessels.

Why Are Blue Eyes More Sensitive To Light?

Why Do Your Eyes Need Sun Protection?

Eyes of all colors need shielding from the sun’s harmful ultraviolet (UV) rays. Exposure to UV light can contribute to the formation of short-term and long-term eye conditions such as corneal sunburn and macular degeneration.

That’s why it’s so important to choose high-quality Sunwear with 100% UV blocking lenses and to throw on a sun hat for an added layer of protection.

UV protection is important for individuals of all ages—especially children—who are more susceptible than adults to the sun’s harmful rays and tend to spend more time outdoors. It is estimated that up to 80% of a person’s lifetime exposure to UV rays happens before the age of 18.

Why are Blue Eyes More Sensitive to Light?

Lighter-colored eyes like blue, hazel, and green have less of a pigment called ‘melanin’ than brown eyes do.

Melanin helps protect the retina from UV damage and blue light, putting those with blue eyes at a higher risk of developing UV-related eye damage.

If you have blue eyes, you may have experienced this first-hand. Bright light may be uncomfortable or you may want to reach for your shades as soon as you leave the house on a sunny day.

That’s why optometrists urge blue-eyed patients to be particularly vigilant about UV protection, so as to mitigate their chances of developing eye disease and other complications.

Should I wear sunglasses even when it’s not sunny outside?

Yes! You should wear your sunglasses whenever outdoors during the day, even on an overcast, winter day. UV light can pass through clouds and reflect off surfaces like car windows and pavement.

What type of sunglasses are the most suitable for blue eyes?

The most protective sunglasses are wraparound sunglasses that protect the eyes from every angle. You can also opt for photochromic lenses, which offer total UV protection but only become tinted when exposed to outdoor sunlight, and turn clear when you come indoors again. Your optometrist can help you choose the best lens and frame options for your needs and lifestyle.

Why Are Dilated Eye Exams So Important?

Having your eyes dilated during an eye exam may seem like a nuisance. But when you consider the benefits of a dilated eye exam, the temporary blurred vision and sensitivity to light that typically follow are definitely worth it.

What Are Dilated Eye Exams?

At some point during a comprehensive eye exam, your optometrist will shine a bright light into your eyes to examine the back of your eye, called the retina. The problem is that bright light causes the size of the pupil’s opening to shrink, which makes it hard for the optometrist to see a large portion of the retina.

That’s why eye doctors apply special eye drops in each eye to keep the pupils open. A dilated pupil allows for a much more accurate assessment of your eye’s structures, including the focusing lens, blood vessels and tissues at the back of the eye called the retina, as well as the optic nerve and macula.

Dilating the eyes makes it easier for your optometrist to detect the following conditions and diseases:

It’s important to note that many of these conditions can develop without noticeable symptoms, until they cause vision loss at which point treatment may be more challenging, making dilated eye exams all the more crucial.

The Dilation Process

First, your eye doctor will apply eye drops to each eye to trigger dilation of the pupil. Your eyes should be fully dilated about 10-20 minutes later.

Your eyes will remain dilated for 4-6 hours, and during this time you may be sensitive to light. That’s because the larger pupil allows more light than usual to enter the eye. Many patients find it more comfortable to wear sunglasses until their eyes return to normal.

Reading and using a computer may be difficult with dilated eyes, and your vision may be blurred. Some patients report feeling a tightening sensation in their eyelids, or headaches.

Dilated eye exams are a crucial part of keeping your eyes healthy. To schedule your comprehensive eye exam, call Dr. Patricia Fink Optometry in Burlington today!

At what age should one have a dilated eye exam?

You should have your dilated eye exam no matter your age. Most eye doctors will dilate a new patient at their first exam regardless of age to get a baseline of their retinal health.

Will I be able to return to work after a dilated eye exam?

Everyone reacts differently, so it’s hard to tell. If your job requires you to focus on small print or detail, it may be challenging. Typing and writing may also be difficult with dilated pupils. To be on the safe side, book your appointment at the end of your work day, clear your schedule after your eye exam and only plan to do activities which aren’t visually demanding.
